Just for an update: I finally got the lens three weeks ago. Unfortunately, weather conditions have not been very useful for great photos since then, however i managed to take some test shots in the meantime. The Sony Version has an integrated profile for correction of CAs and I could not find distortion issues either. I will take a lot more photos with this lens tough, when sunlight is available. Here is another shot from the Speicherstadt in Hamburg as an example of use in architecture, taken with my Sony A7III, showing sheets of ice on the channel Kehrwiederfleet.
